Fig. 4. Dkk1 is a downstream target of the GATA4-FOG2
transcription complex. (A,B) qRT-PCR analysis of
Dkk1 expression was performed with wild-type (A) or wild-type and
Fog2-/- (B) gonad-mesonephros samples. (C-L) ISH
was performed with a Dkk1 RNA probe on XX and XY gonads from
wild-type, Gata4ki/ki and Fog2-/-
E11.5-13.5 mouse embryos as indicated.
